Cautions during Installation
• Be sure to install this product by following the usage environment, location, and
specified ratings. Consider the listed conditions below.
- Installation environment and background (reflected light)
- Sensing distance and sensing target
- Direction of target's movement
- Feature data
• If the installation environment has reflected light from the wall or floor, a interval
distance of at least 0.3 m is required.
• When installing multiple sensors closely, it may result in malfunction due to mutual
interference. Install it by referring to the interference protection and the installation
method in the manual.
• Do not use in places where the light-receiving sensor is exposed to direct sunlight or
where the ambient illumination is higher than the specification.
• Do not impact with a hard object or bend the cable excessively. That could decrease
the product's water resistance.
• Use this product after the test. Check whether the indicator works appropriately for
the positions of the detectable object.

Over current
• The operation of 'Operation indicator (red)', 'Job indicator (red)', 'Control output' is for Light ON, in case of
Dark ON, it is opposite operation against Light ON.
• Malfunction of synchronous line and over current, control output is OFF regardless of the mode.
